The Charles County Sheriff’s Office is renewing its call for information in the 1974 murder of George Allen MacDonald, whose body was discovered near Trinity Lake in La Plata more than 50 years ago.
In February 1974, deputies responded to the shores of Trinity Lake near Dubois Road in La Plata, Charles County, Maryland, where they found the body of a deceased male. The victim was identified as 26-year-old George Allen MacDonald, a resident of Riverdale in Prince George’s County.
Investigators determined that MacDonald had attended a party in Prince George’s County around Halloween 1973. Evidence suggests he may have been involved in a fight during or after the event. Authorities believe the killing occurred at the party or shortly afterward, and that MacDonald likely knew his killer or killers. No witnesses reported seeing him after the gathering, leaving a critical gap in the timeline.
The case remains unsolved, but detectives with the Charles County Sheriff’s Office continue active efforts to resolve it. They are particularly interested in speaking with anyone who attended the Halloween party or has any details about MacDonald’s activities that night or in the following days.
To encourage new leads, the sheriff’s office is highlighting the case as part of its Pursuit of Justice series focused on cold cases. Anyone with information can contact Charles County Crime Solvers at 1-866-411-TIPS. Tips can be submitted anonymously. CCSO and Crime Solvers are offering a reward of up to $10,000 for information leading to an arrest or indictment in the case.
This renewed appeal comes amid ongoing work by the sheriff’s office to reexamine older homicides for potential forensic advances or overlooked witness accounts. MacDonald’s death marks one of the longer-standing unsolved killings in the region, underscoring the challenges of investigating crimes from an era before widespread DNA technology and digital records.
The sheriff’s office has not released additional details on current investigative steps, but the public call signals confidence that fresh information could break the case open. Similar efforts in other cold cases have occasionally yielded breakthroughs when longtime witnesses come forward.
